Hello,
First of all, apologies for my terrible English...
Maybe I'm really stupid, but looks like something is wrong with my system...

It's a Windows 7 32 bit. I've done everything.. Freetrack open, running and tracking correctly with my PS3 Eye camera... then I launch X-plane 11, check the "enable trackir or track hat bla bla bla" checkbox... load the plane and start the simulation... but... nothing... x-plane 11 POV camera in 3d cockpit wont move and nothing... I've tried with the OpenTrack Software, and with that software It works fine!... But I dont like that software and wanted to make it work with the Freetrack 2.2 version... any ideas?

the reason why I think you can't get it working is because X-plane uses the sim-connect protocol which has had a few update since the developement stopped of Freetrack in 2008.Opentrack and Ftnoir(facetracknoir) had the same problem a few month ago but are still further developed and updated and that problem was also fixed.
Iam afraid that you have to stick with Opentrack or give Ftnoir a try.Opentrack is free to use, Ftnoir costs €2,85.
Wich one is better??That is what you personally decide yourself.I use Ftnoir because it supports two tracking sources at the some time.I use an Edtracker wich has only 3dof and for the other 3dof I use axis of my joystick.
